But there won't be any HELLO message coming from the sending side since the

sending side should provide HELLO messages with the same format as
Yes, obviously. It's the same thing as with ftp: If your ftp client does
not know how to handle control and data connection, it can't connect to
machine has more than one ethernet card, you may also pick which
card to use using the -i option. This influences the unicast adress that
the receiver uses.
As far as I know, by default, udp-receiver listens for its unicast address
as well. Is udp-receiver capable of listening every UDP packet coming to its
port numbered 9000 without expecting any HELLO message from the other side ?
No, the HELLO packet is an integral part of the protocol. Just like ftp
can't do without a control connection, udpcast can't do without HELLO.
